3.Output Voltage TRIM
(1)Connecting an external DC source between PV and-S on CN1 or CN2 that is shown in Fig. 3.1.
(2)Adjustment of output voltage is possible between 20~110%(Typ.) of the rated output which is shown in Fig. 3.2. Reducing output current is required when the
output voltage is trimmed up.
2.Alarm Signal Output
(1)Alarm signal is sent out through "P OK" & "P OK GND" and P OK2 & P OK GND2 pins.
(2)An external voltage source is required for this function.
(3)Table 2.1 explain the alarm function built-in the power supply.

P OK
The signal is "Low" when the power supply is
80% of the rated output voltage-Power OK above
Low (0.5V max at 500mA) Low (0.5V max at 10mA)
Description Output of alarm(P OK, Relay Contact) Output of alarm(P OK2, TTL Signal)
The signal turns to be "High" when the power supply
is under 80% of the rated output voltage-Power Fail High or open
(External applied voltage, 500mA max.) High or open
(External applied voltage, 10mA max.)
